ROC curve analysis. Comparison of area under the curves (AUCs) between ELISA (BAMILE, TAUE, PTAUE) and xMAP (BAMIL, TAU, PTAU) analysis results. No significant differences between AUCs (𝑃<0.05). Sensitivity % (at 80% specificity): ELISA: A𝛽_1--42 = 90; Tau protein = 85; P-tau protein = 84 xMAP: A𝛽_1--42 = 82; Tau protein = 83; P-tau protein = 85.
